Now that you understand the basics of Arduino, including the different connectivity options available and the communication protocols, you are going to use that knowledge to prototype IoT applications.
This chapter starts with a hypothetical scenario. Imagine that you are responsible for monitoring noise levels around an animal sanctuary. Whenever noise levels cross a certain threshold, you are required to send an SMS to the supervisor and log noise information in a database for future trends analysis. Let’s look at what will it take to implement this IoT application: ...
